The synthesis of lactose-containing dendrimers is described; the dendrimers used were based on the 3,5-di(2-aminoethoxy)benzoic acid repeating unit. Dendrimers of generation 1, 2, and 3 − containing 2, 4, and 8 endgroups, respectively − were used. These were coupled to lactose isothiocyanate, resulting in thiourea-linked glycodendrimers, characterized by 13C NMR and mass spectrometry. The lactose-functionalized
描述了含乳糖树枝状聚合物的合成;使用的树枝状聚合物基于 3,5-二(2-氨基乙氧基)苯甲酸重复单元。使用了分别包含 2、4 和 8 个端基的第 1、2 和 3 代树枝状聚合物。这些与乳糖异硫氰酸酯偶联,产生硫脲连接的树枝状大分子,其特征在于 13C NMR 和质谱。通过荧光测定评估乳糖官能化的树枝状聚合物结合霍乱毒素 B 亚基的能力。在荧光测定中确定的结合亲和力 (Kd's) 范围从单价乳糖的 18 mM 到八价乳糖树枝状聚合物的 33 μM。
